# Hole in the Wall!

A large tank is filled with water (density $$\rho$$). A small hole is made at a depth of $$h = 10m$$ below the water surface. The range of water issuing out of the hole is $$R$$ on ground. What Extra Pressure (in atm) must be applied on the water surface so that the range becomes $$2R$$?

Details and Assumptions:

$$\bullet$$ The answer to this problem is an Integer
$$\bullet \rho = 10^3 kg/m^3$$
$$\bullet g = 10 m/s^2$$
$$\bullet$$ Water is assumed to be ideal liquid
